INSULATOR.

Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed May 28, 1907. Serial No. 876,078.

T 0 all whom it may concern:

Be it known that I, LAWRENCE L. BOGUE, citizen of the United States, residing at East Orwell, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Insulators, of which the following is a specification.

This invention relates to electric circuits, and more particularly to insulators for use therein, and has for its object to provide an insulator which will be simple and cheap, which may be molded with little difficulty and which will insure complete insulation of a wire supported thereby.

Another object is to provide an insulator arranged to be supported by a wire.

Other objects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a perspective view of the present insulator in use; Fig. 2 is a section taken through the insulator in the plane of the horizontal groove.

Referring now to the drawings, the present invention comprises a body portion 5 having the form of an ellipsoid, in which there are formed a pair of longitudinally extending continuous grooves 6 and 7 respectively. These grooves intersect at the ends of the body portion, as shown, the groove 7 being of greater depth than the groove 6 at the end of the body portion indicated by the letter A, while at the end indicated by the letter B, the groove 6 is of greater depth than the groove 7. The arrangement is thus such that a wire engaged in the groove 6 will lie inwardly of the plane of a wire in the groove 7, at one end of the body portion, and outwardly of the plane of such wire at the other end of the body portion. Thus wires in the two grooves will be held positively in spaced relation at the points at which they cross.

In use, a wire is engaged in each of the grooves, such wires being looped around the body portion, each wire having its portions twisted together at the end of least depth of the groove in which it is engaged. In

the drawings, a wire X is engaged in the groove 7 and a wire Z is engaged in the groove 6, the former being the supporting wire while the latter is the line wire.

It will be seen from the foregoing that the two wires engaged with the body portion are fully insulated from each other and that the insulator is such as may be readily and quickly installed. As shown, the grooves 6 and 7 are spaced from each other 90 on the minor circumference of the ellipsoid.

What is claimed is:

An insulator comprising an elongated body cylindrical in cross section and having rounded ends, the body having continuous U shaped grooves formed therein intersecting at the rounded ends of the body, one of the grooves being of a greater depth at one of the rounded ends of the body and the other groove being of greater depth at the other rounded end of the body, a wire looped around the body and engaged in one of the grooves, the wire having portions twisted together at a point of intersection of the grooves at one end of the body, in combination with a supporting wire looped around the body and engaged in the other of said grooves, the wire having portions outwardly of one end of the body twisted to form an elongated strengthening portion, the last named wire having post engaging portions outwardly of the twisted ends.

In testimony whereof I afiX my signature, in presence of two witnesses.
